how would you describe the relationship between brutus and portia

Their relationship is actually quite loving. In this scene Portia actually wakes up to have a little couple’s chat about the state of things. Portia knows Brutus is hiding something and implores him to share his burden. I'm going to go the romantic route and say that Brutus doesn't want to tell Portia because he does not want to involve her in this very dangerous conspiracy. Portia wants to know about the masked men, the secret chats...She says that she is his friend and wife rather than a kept woman. This bond is rather uncharacteristic of nuptial relationships during this period but it is nice to read!
